A thermoelectric module includes an insulating substrate, plural electrodes formed on a component side of the insulating substrate, plural peltier elements each mounted on and electrically connected to the electrodes, and a mark for image recognition formed at least one of the electrodes, the mark for image recognition having lightness and/or saturation which is different from lightness and/or saturation of the electrode on an image. An entire of the electrode is usable as an electrical conduction path.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A thermoelectric module, comprising: an insulating substrate; a plurality of electrodes formed on a component side of the insulating substrate; a plurality of peltier elements each mounted on and electrically connected to the electrodes; and a mark for image recognition formed on at least one of the electrodes, the mark for image recognition having lightness and/or saturation which is different from lightness and/or saturation of the electrode on an image; wherein an entire of the electrode is usable as an electrical conduction path, the mark for image recognition is a plating layer of the at least one of the electrodes, the plating layer is an electroless plating film or an electroplating film, the electrode includes a fixture side facing the insulating substrate and a component side provided at a reverse side of the fixture side, the component side of the electrode includes a mounting region on which the peltier elements are mounted and a general region which is a region other than the mounting region of the electrode, the mark for image recognition is formed on the general region of the electrode, the mark for image recognition includes a protruding configuration that is formed on at least a portion of the general region of the electrodes, and a length of the mark for image recognition from the component side in a thickness direction of the electrode is shorter than a length of the peltier elements from the component side in the thickness direction.
2. The thermoelectric module according to claim 1 , wherein the mark for image recognition includes a plurality of marks for image recognition and each of the marks for image recognition is formed on the separate electrode.
3. The thermoelectric module according to claim 1 , wherein the mark for image recognition is a black nickel plating.
4. The thermoelectric module according to claim 1 , wherein an entirety of the mark for image recognition is between the peltier elements.
5. The thermoelectric module according to claim 1 , wherein the mark for image recognition is between the peltier elements and extends an entire width of the electrode.
